Abstract

Five SMAW consumables were evaluated as candidates for repairing weld-zone corrosion in Canadian Coast Guard ships constructed of Grade A, Grade E and Grade EH steels on the basis of mechanical properties and corrosion resistance. A spectrum of corrosion rates was observed but several electrodes were found to be compatible with all baseplates including Grade EH containing 1.39% Mn.
